Make a list of conventional and non-conventional sources of energy. Give a brief description harnessing one non-conventional source of energy.

Explanation

The following are the list of conventional and non-conventional sources of energy
(i) Conventional sources of energy They are those which are used extensively and meet a major portion of our energy requirement. These are fossil fuels (wood, coal and petrol), hydro energy, biomass energy and wind energy.
(ii) Non-conventional sources of energy They are those which are not used as extensively as conventional ones and meet our energy requirement only on a limited scale. These are socal energy, ocean energy (tidal energy, wave energy and ocean thermal energy), geothermal energy and nuclear energy.
The harnessing of one non-conventional source of energy is as follows
Nuclear energy Nuclear energy is produced by the release of heat from unstable elements such as uranium. The energy is harnessed by using the energy to heat water.
The radioactive water is then pumped through a heat exchanger where the dirty water is used to heat clean water. The clean water can then be used to derive turbines and other forms of engine.
